22 | /// based on the standard definition of the detector elements in | |
23 | /// $ALICE_ROOT/MUON/data | |
24 | /// | |
25 | /// --> User has to specify the magnitude of the alignments, in the Cartesian | |
26 | /// co-ordiantes (which are used to apply translation misalignments) and in the | |
27 | /// spherical co-ordinates (which are used to apply angular displacements) | |
28 | /// | |
29 | /// --> If the constructor is used with no arguments, user has to set | |
30 | /// misalignment ranges by hand using the methods : | |
31 | /// SetApplyMisAlig, SetMaxCartMisAlig, SetMaxAngMisAlig, SetXYAngMisAligFactor | |
32 | /// (last method takes account of the fact that the misalingment is greatest in | |
33 | /// the XY plane, since the detection elements are fixed to a support structure | |
34 | /// in this plane. Misalignments in the XZ and YZ plane will be very small | |
35 | /// compared to those in the XY plane, which are small already - of the order | |
36 | /// of microns) | |
37 | /// | |
38 | /// Note : If the detection elements are allowed to be misaligned in all | |
39 | /// directions, this has consequences for the alignment algorithm | |
40 | /// (AliMUONAlignment), which needs to know the number of free parameters. | |
41 | /// Eric only allowed 3 : x,y,theta_xy, but in principle z and the other | |
42 | /// two angles are alignable as well. | |
